In a move out of nowhere, Toshiba just announced the limited release of a "concept" device with almost the exact same form-factor as the Microsoft Courier. The Libretto W100 features dual 7" multi-touch screens that fold out flat or clap together like a book. Those wanting the full Courier experience, be prepared for disappointment, however: no pen support is present, and the OS is stock Windows 7 Home Premium--albeit with the addition of some pretty slick-looking touch-friendly widgets.

Perhaps the most interesting part is the virtual keyboard concept--the touch of a button turns the bottom screen into a haptic keyboard with either a standard layout for laptop approximation, or an alternate layout that looks to be thumb-friendly. In terms of performance, it should theoretically beat most Atom-based netbooks with its dual-core, 1.2GHz Pentium U5400 processor (essentially a kind of Core i3 lite) and 62GB SSD. The price tag for this stylish harbinger of things to come? A cool $1,099. Also see Engadget's coverage
